Sellier & Bellot 12 Gauge Breaching Rounds are the professional choice for rapid, controlled entry and emergency egress. Featuring a 1/2 oz Firearm Ammunition polymer projectile, these rounds are pushed at a blistering 1,673 fps to ensure hinges and locks are defeated instantly. The specialized material is designed to disintegrate upon contact with hard barriers, significantly reducing the danger of ricochet in confined spaces. Packaged in a 10-round box, this ammunition is an essential addition to a tactical loadout or home emergency kit, providing the specialized capability to navigate through locked barriers when every second counts. Safety Warning: Breaching rounds are not self-defense projectiles for direct fire against intruders. Their Firearm Ammunition nature means they lack the stopping power and penetration required for reliable incapacitation. Never fire these rounds through a choked barrel; they are intended for Cylinder Bore (un-choked) barrels only.
